Promaster 67mm 可変NDフィルター - Basis (2 - 8 段)

I was skeptical about variable ND filters, but the smooth rotation between 2 and 8 stops on this one makes quick exposure adjustments effortless. It's sharp across the whole range, with no noticeable color cast even at the strongest setting.

Switching from a fixed ND to this variable has been so much smoother on hikes, just a quick twist to adjust exposure instead of swapping filters. The 2 to 8-stop range gives me plenty of flexibility for everything from waterfalls to bright sunny landscapes, and the image quality stays surprisingly c

Works well for controlling exposure in bright sunlight, though the ring is a bit stiff to turn smoothly. I like that it covers 2 to 8 stops without introducing color cast.
